There are few things people love more than a good diva-off (see: 10 to 12 episodes of Glee) and Madonna never fails to disappoint. Perhaps you thought the controversy about "Express Yourself" and "Born This Way" sounding like the same damn song was over, but today Madonna revived the feud by calling Lady Gaga's effort "a wonderful way to redo my song." Earlier this week, Madonna took the high road, telling Graham Norton, "When I first saw [Gaga] I was really impressed by her and she was cool ... She did remind me of me back in the day." Yet, when Newsweek asked about "Born This Way," Madonna said, "I thought, this is a wonderful way to redo my song ... I mean, I recognized the chord changes. I thought it was ... interesting." And of course, "interesting" is code for "bullshit." Presumably the ladies will resolve this by making out in some kind of public forum. [Daily Beast via N.Y. Mag]

So supposedly Robert Kardashian is speaking to TMZ from beyond the grave to insist that Khloe really is his daughter. All he did was say in divorce papers that his marriage to Jan Ashley didn't work because she wanted a child and "I decided that since I already had four biological children, I did not wish to have any more." But, that's pretty much the same as submitting to a DNA test. [TMZ]

Somehow we doubt this is true, but the story's still amusing. J.Lo allegedly has her kids calling her 24-year-old boyfriend Casper Smart "Daddy Casper." When Marc Anthony found out he flipped, as he's wont to do, and a source says he "mockingly told Jennifer that if Casper wants to be called ‘Daddy,' he needs to start acting like it and pay some of their children's expenses instead of just sponging off of her!"

Kim Richards is out of rehab and a source says she only checked herself in to remain a Real Housewife: "Kim was basically told that if she wanted to stay on the show then she had to get help, so she did. Kim doesn't have any other significant source of income and she needs to keep her job on the show." [Radar]

Susan Lucci is sort-of returning to the world of soaps by hosting the prime-time cable series Deadly Affairs on "deceptive love relationships, love triangles and betrayal that have deadly consequences." I think we need an appearance from Michael Nader so he can explain what it's like when Lucci pretends to stab you with a letter opener. [AP]
